[asterisk-users] How to detect line tone?

[Massimo Nuvoli]

I need in a strange applicatio a way to "detect" the tone (busy, ring
etc. etc.) of analog line (zap channel), while channel UP.

I found the application "NV" line detect, but is very old, and may be
not mantained.

I can patch asterisk to actually support this application but i think
someone other have something like this done.

Thnks.
